MEANS FOR TRANSMITTING POWER FROM TI-KIE AXLES OF RAILWAY-CARSi Application filed June 29, 1907. Serial No. 381,476.

To all whom it may concern:

Be it known that l', lit-xwnaxea (J. Mun-1n, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and

have invented a certain new and useful improvementin mean:

for transmitting power from the axles of describe its construction i truck, and (7 railway-ears and the like to electric generators and for stopping and starting the generator while the axle is in motion, of which the following is a specification. .\fy invention relates to a new and useful means for transmitting power from the axles of railway cars and thelike to electri and starting t in motion. 7

With theseends in view, this invention of construction and elements hereinafter set fically designated by the cmnbination of forth and then speci claims.

.ln order'that those skilled in the art to which this invention appertains may understand how to make and use the same, I will i n detail, referring byletter to the accompanying.drawing form ing a part of this specification, in which Figure lis a sectional elevation of a portion of a car and truckshowing my improve-- ment applied thereto. Fig. 2, a similar view taken atright angles thereto.

in carrying out my invention as bodied, A represents a friction or gear wheel secured upon one of the axles B of the is a small wheel adapted to engage with the wheel: A and receive power therefrom. "he wheel (I is secured upon a shaft 1), which is journalcd in suitable bearings formed upon the armature l), and to this shaft is secured a flexible shaft 1, the opposite end of which is connected to the. he 'electrie generator (l, the latter being secured to the under side of the ear. By this arrangement power is transmitted to the generator whenever the car is here emin motion, and the movements of the truck relative to the body of the car are compensated for by the flexible shaft, as will be .In order that the generator may be put l l l e generators, and for stopping he generator while the axle ls Specificati'onof Letters Patent.

into or out of action while the ear is running, 1 )rovide an electro magnet II so arran ed re ative to the armature E that when t is magnet is vitalized it will draw the armas ture upward against the action of the spring I, thus lifting the wheel (I out of engagement with the wheel A, which will stop the rotation of the flexible shaft and consequently the generator. The wires of this magnet pass-into the car and may be connected with a suitable switch, the operations of which will make or break a suitable electric circuit for energizing or tie-energizing the magnet.

in practico,when the generator is used for charging a storage battery upon a cut, suitable automatic switches may be included in the circuit, and when the battery has been fullycharged the magnet ll may be'vitalized, thereby drawing the wheel out of contact or mesh with the w rator to stop, thus cutting off the further charging of the battery, or if preferred an ordinary hand switch may be used forsending a current through the magnet ll forstopping the generator.- I

It is to be understood that the wheels and-f may be gears and adapted to mesh to gether, or they may be fri tion wheels adapted to transmit the m tion of the ar axle to the generator by the pressure ol one upon the other caused by the spring ll Having thus fully described my invention, what l claim as new and useful. is

in combination with a generator carried by the body ofa car. a ivheel. a flexible shaft connecting said generator and wheel. a driving wheel secured upon the axle of the car, a spring for forcing the driven wheel in contact with the driving wheel, an armature upon which the driven wheel is journaled and an electro-magnet so arranged as to draw the armature upward and thereby lift the driven wheel out of contact with the driving wheel when said magnet is vitalized, as specified.

in testimony whereof, I have hereunto affixed my signature in the presence of two subscribing witnesses.
